So it is Finals week for PComp and I can't wait to complete my project. Copper tape became the hero of this project since I am trying to create circuits by pushing conductive surfaces against each other. The technical part is really simple. Each cube has an open circuit inside but when it is pushed against a conductive surface polarized by 5V and Ground, it starts to function.

In this test The cube is working with an LED inside now I have to figure out how to execute the cubes.

I have couple of ideas though :) Here are some examples.
